A method and apparatus are provided for interpolating image lines from ultrasonically obtained scanlines of an image region. The interpolated lines are preferably formed one-quarter and three-quarters of the distance between each pair of received scanlines by combining weighted samples of the adjacent scanlines in proportion to their distances from the interpolated lines. The received scanlines are preferably formed by a beamformer which samples the received lines at quadrature phases of the scanhead center frequency and filters the samples by combining successive samples of a related phase. The image lines are scan converted by computing a grid of weighted values between each pair of image lines, and using the closest value for each pixel in the ultrasound image.

Méthode et dispositif permettant d'interpoler des lignes image à partir de lignes de balayage d'une plage d'affichage obtenues par ultrasons. Les lignes interpolées sont créées de préférence au quart et aux trois-quarts de la distance entre chaque paire de lignes de balayage reçues en combinant des échantillons pondérés des lignes de balayage adjacentes en proportion de leur distance par rapport aux lignes interpolées. Les lignes de balayage reçues sont formées de préférence par un formeur de faisceaux qui échantillonne les lignes reçues en quadrature avec la fréquence centrale de la tête de balayage et filtre les échantillons en combinant des échantillons successifs d'une phase connexe. Les lignes image sont traitées par convertisseur de balayage en calculant une grille des valeurs pondérées entre chaque paire de lignes image et en utilisant la valeur la plus rapprochée pour chaque pixel de l'image ultrasonore.
